A case study on pollution and a human health risk assessment of heavy metals in agricultural soils around Sinop province, Turkey
(Pergamon-Elsevier Science Ltd, 2020)
In the present study, the concentration levels of heavy metals such as Cr, Fe, Ni, Cu, Zn, As and Pb in soil samples collected from 88 sampling locations around Sinop Province, Turkey were measured using energy dispersive ...
Quantum emitter interacting with graphene coating in the strong-coupling regime
(Amer Physical Soc, 2020)
We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are based on solutions of three-dimensional Maxwell equations, using a boundary element method approach. ...
Density functional theory investigation of oxidation intermediates on gold and gold-silver surfaces
(Amer Chemical Soc, 2020)
Gold and gold-silver alloys can be active and selective oxidation catalysts. Previous work has suggested that O-2 dissociation occurs at bimetallic step sites on gold-silver alloys, but the site responsible for the rest ...
Dynamic critical phenomena in a multilayer Ising system
(Elsevier, 2020)
Using the mixed-spin system, we precisely calculate the dynamic critical phenomena, namely dynamic compensation behaviors, dynamic phase diagrams and dynamic hysteresis loops in a multilayer Ising system that composes of ...
First-principles investigation of CO and CO2 adsorption on gamma-Al2O3 supported monoatomic and diatomic Pt clusters
(Elsevier, 2020)
Supported clusters of transition metal atoms are key components of heterogeneous catalysts. Understanding their interaction with small molecular species is therefore an important step in catalyst design. in this work, we ...
The effects of the intense laser field on the resonant tunneling properties of the symmetric triple inverse parabolic barrier double well structure
(Elsevier, 2020)
Transmission properties of an electron in the symmetric triple inverse parabolic barrier double well structure have been investigated under the intense laser field. We have found that the laser field has effects on tunneling ...
Trapped magnetic field and levitation force properties of multi-seeded YBCO superconductors with different seed distance
(Elsevier Science Sa, 2020)
The performance of large grain (RE)BCO superconducting bulks has the significant potential for magnetic-force based applications such as trapped field magnets and magnetic levitation devices. These materials can trap high ...
Evaluation of gamma attenuation parameters and kerma coefficients of YBaCuO and BiPbSrCaCuO superconductors using EGS4 code
(Pergamon-Elsevier Science Ltd, 2020)
The levels of the coefficients of the mass attenuation (mu/rho) for YBaCuO and BiPbSrCaCuO superconductors and their contents were determined theoretically, using EGS4 simulation code and the XCOM database, and experimentally ...
Structural, morphological, optical analyses of Ni-doped CdS thin films and their photovoltaic performance in hybrid solar cells
(Springer, 2020)
This work reports influences of variation in Ni-doping on structural, morphological, and optical properties of CdS thin films and in their hybrid solar cell applications. X-ray diffraction data showed that increase of ...
